In rural India, getting healthcare is not as simple as walking into a clinic. For millions living in remote villages, the nearest hospital can be hours away, and awareness about preventive care remains low. This is precisely where Community Health Workers (CHWs) step in – trained, community-based individuals who bring essential health services directly to people’s doorsteps. Within the framework of Sustainable Community-Based Rehabilitation (SCBR), CHWs are the backbone of primary health care delivery, particularly in underserved areas where formal health infrastructure is thin.

The role of community health workers in primary health care
CHWs serve as the frontline link between rural communities and the broader health system. They do not simply deliver medicines – they educate, mobilize, screen, refer, and follow up. Their work spans promotive, preventive, curative, and rehabilitative health services, making them indispensable to any community-based approach to health and rehabilitation.
In the context of primary health care, CHWs run awareness programs on disease prevention, hygiene, sanitation, nutrition, and safe motherhood. They organize and assist in health camps, accompany patients to facilities, maintain health records, and act as trusted community voices that formal health systems often cannot replicate. India’s ASHA program alone represents the largest all-female community health worker program in the world, reflecting just how central this workforce is to the country’s public health ambitions.
The World Health Organization defines CHWs as individuals selected by and accountable to the communities they serve, supported by – but not necessarily part of – the formal health system. This positioning allows them to reach populations that institutional care often misses, building trust through cultural familiarity and consistent presence.
Types of community health workers in India
India’s rural healthcare delivery system relies primarily on three cadres of frontline workers: Auxiliary Nurse Midwives (ANMs), Accredited Social Health Activists (ASHA workers), and Anganwadi Workers (AWWs). Each cadre has a distinct role, but together they form a complementary network that covers maternal health, child development, immunization, nutrition, and community education.
Auxiliary Nurse Midwives (ANMs)
ANMs are the first formally trained cadre, based at sub-centers – the lowest facility level in the rural public health system. They receive 18 months of training and are responsible for family planning, immunization, antenatal care, and conducting deliveries. ANMs conduct monthly outreach visits to villages, focusing on maternal and child health. They also supervise ASHA workers by informing them about outreach session schedules and assisting with health days at Anganwadi centers. ANMs based at sub-centers serve populations of over 10,000 from four to five villages, giving focused attention to health promotion in their jurisdiction.
ASHA workers
The ASHA program was launched in 2005 as the cornerstone of the National Rural Health Mission (NRHM), with the goal of recruiting one female volunteer per village to serve as a health educator and promoter. Each ASHA is a resident of the village she serves, which gives her a natural credibility and access that outside workers rarely enjoy. Their responsibilities include promoting universal immunization, providing referral and escort services for reproductive and child health programs, and counseling women on birth preparedness, safe delivery, breastfeeding, and contraception. ASHAs are also equipped with a basic drug kit for first-contact care and receive performance-based incentives for activities such as facilitating institutional deliveries and completing child immunizations. In several states, their roles have expanded to include non-communicable disease screening, such as listing individuals with hypertension, diabetes, and cancers.
Anganwadi Workers (AWWs)
AWWs are the key functionaries of India’s Integrated Child Development Services (ICDS) scheme, operating out of Anganwadi centers that function as village-level preschools and nutrition hubs. Their work is focused on providing food supplementation to children under six, adolescent girls, and lactating women, as well as offering health and nutrition education to pregnant women and new mothers. AWWs and ASHA workers coordinate health days once or twice a month, updating lists of eligible couples and young children and mobilizing nursing mothers and infants for nutrition support. AWWs also conduct growth monitoring sessions to track child development and identify early signs of malnutrition.
Health camps and early intervention
One of the most visible contributions of CHWs in primary health care is their role in organizing and supporting health camps. These are periodic outreach events held directly in villages or community spaces, often in areas where there are no nearby clinics or hospitals. For many rural residents, health camps are the first point of contact with organized medical care, and they serve communities that have long been on the peripheries of the formal health system.
Medical screening camps focus on early detection and intervention, especially for vulnerable groups including children, the elderly, and those with disabilities. Services typically include general health check-ups, blood pressure and blood sugar monitoring, hemoglobin testing, immunizations, eye and ear screenings, and nutritional assessments. In the context of rehabilitation, these camps also include disability screening – a critical step in identifying children or adults with developmental delays or physical impairments who would otherwise go undiagnosed for years.
Early intervention is especially significant for disability prevention and management. India’s District Early Intervention Centers (DEICs) rely on community screenings as one of their primary referral pathways, accepting children identified with developmental delays or birth defects for comprehensive assessment and therapy. CHWs are often the first to identify such children during routine home visits or health camp screenings, making them critical to the early intervention pipeline.
Health camps also carry a strong awareness component. Camps involve diagnostics and screenings alongside education on conditions such as diabetes, hypertension, and nutrition, and these one-to-one interactions often mark the beginning of a community’s health literacy journey. Beyond treating existing conditions, this educational role directly supports the preventive mission of community-based rehabilitation.
Maternal and child health: a core focus
Maternal and child health is not just one component of a CHW’s work – it is the central axis around which most of their activities revolve. CHWs have been acknowledged as primary factors in achieving better neonatal, maternal, child, and adolescent health outcomes across India. Given that improving these outcomes is also a foundational goal of sustainable community-based rehabilitation, the alignment between CHW work and SCBR principles is direct.
Antenatal and postnatal care
ASHA workers encourage pregnant women to attend a minimum of four antenatal care (ANC) visits, give birth in institutional settings, and access postnatal care. Research has found that mothers who received coordinated counseling from both ASHA and AWW workers had significantly better outcomes in birth preparedness, institutional delivery, and postnatal care visits compared to those who received counseling from only one cadre. This confirms the value of the “AAA platform” – the convergence of ANM, ASHA, and AWW services – in achieving comprehensive maternal health coverage.
Child nutrition and growth monitoring
CHWs are the frontline workforce linking communities to formal health systems and educating women on infant and child feeding practices in their areas. AWWs conduct monthly growth monitoring sessions at Anganwadi centers, tracking the weight and development of children under six to catch early signs of malnutrition. India’s national approach to community-based management of acute malnutrition integrates screening, identification, and care through frontline functionaries of the departments of Women and Child Development and Health and Family Welfare. This ensures that severely malnourished children are not only identified but also connected to treatment services.
Immunization and disease prevention
Immunization is one of the most impactful services delivered through the CHW network. ASHAs have been credited with increasing both the rate of institutional deliveries and the uptake of vaccinations across India. ASHA workers assist ANMs during immunization days, mobilize mothers and children, and follow up on those who have missed scheduled doses. This consistent community-level push has been essential in reducing vaccine-preventable diseases, particularly among children under five who are most vulnerable.
Hygiene and preventive health education
CHWs also conduct regular home visits to promote safe hygiene practices, clean drinking water, proper sanitation, and healthy infant feeding behaviors. CHWs and community facilitators are involved in education and health promotion activities to empower communities with knowledge and mobilize them to improve their health practices. These activities are not peripheral – they directly reduce the burden of diarrheal diseases, respiratory infections, and malnutrition that disproportionately affect children in rural areas.
The work of CHWs in primary health care is not a standalone effort. It is embedded within a larger system of public health programs, rehabilitation frameworks, and government initiatives that collectively aim to close the gap between rural communities and equitable health outcomes. What makes the CHW model especially powerful within SCBR is its sustainability: these workers live within the communities they serve, build long-term relationships, and continue their work long after external interventions have ended.
What do you think? Given that CHWs often work under challenging conditions with limited remuneration, what systemic changes do you believe are most essential to sustain and strengthen their contributions to primary health care? And how might early disability screening during health camps be better integrated into routine CHW training to improve rehabilitation outcomes in rural communities?
